Geranium plant named ‘Pacsalque’

ABSTRACT

A new and distinct cultivar of Zonal Geranium plant named ‘Pacsalque’, characterized by its compact, upright and uniformly rounded plant habit; freely branching habit; low vigor to moderately vigorous growth habit; leaves with a distinct zonation pattern; early and freely flowering habit; and semi-double light red-colored flowers with white-colored margins.

Botanical designation: Pelargonium×hortorum.

Cultivar denomination: ‘PACSALQUE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium plant, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name ‘Pacsalque’.

The new Zonal Geranium plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to create new uniform and early flowering Zonal Geranium plants with attractive leaf and flower coloration.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2005 of two unnamed proprietary selections of Pelargonium ×hortorum, not patented. The new Zonal Geranium plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Dresden, Germany during the spring of 2006.

Asexual reproduction of the new Zonal Geranium plant by vegetative terminal cuttings in a controlled environment in Dresden, Germany since January, 2007, has shown that the unique features of this new Zonal Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Zonal Geranium have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pacsalque’. These characteristics in combination distinguish ‘Pacsalque’ as a new and distinct Zonal Geranium plant:

-   -   1. Compact, upright and uniformly rounded plant habit.     -   2. Freely branching habit.     -   3. Low vigor to moderately vigorous growth habit.     -   4. Leaves with a distinct zonation pattern.     -   5. Early and freely flowering habit.     -   6. Semi-double light red-colored flowers with white-colored         margins.

Plants of the new Zonal Geranium differ primarily from plants of the parent selections in plant vigor and flower color.

Plants of the new Zonal Geranium can be compared to plants of the Pelargonium×hortorum ‘Pacsalkom’, disclosed in U.S. Plant Pat. No. 20,673. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Zonal Geranium differed from plants of ‘Pacsalkom’ in the following characteristics:

-   -   1. Plants of the new Zonal Geranium were more compact than         plants of ‘Pacsalkom’.     -   2. Plants of the new Zonal Geranium were less vigorous than         plants of ‘Pacsalkom’.     -   3. Leaves of plants of the new Zonal Geranium were smaller than         leaves of plants of ‘Pacsalkom’; in addition, leaves of plants         of the new Zonal Geranium had a distinct zonation pattern         whereas leaves of plants of ‘Pacsalkom’ did not have a distinct         zonation pattern.     -   4. Plants of the new Zonal Geranium were more freely flowering         than plants of ‘Pacsalkom’.     -   5. Plants of the new Zonal Geranium and ‘Pacsalkom’ differed         slightly in flower color.     -   6. Flowers of plants of the new Zonal Geranium had fewer petals         than flowers of plants of ‘Pacsalkom’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Zonal Geranium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Zonal Geranium plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Pacsalque’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers in a glass-covered greenhouse in Dresden, Germany and under conditions which closely approximate commercial Zonal Geranium production. During the production of the plants, day temperatures averaged 18° C., night temperatures averaged 16° C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were three months old when the photograph was taken, and plants were six months old when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
